I don't know veranda, but typically Home Depot pushes vendors so hard, the quality suffers. I know schlage & quickset locks, for example, are made differently.

For the small price difference, I would get Trex, from a lumberyard. Beat up the salesman.

If you want to extend life of the old deck, there are some heavy roll-on coverings that work well, but you are only prolonging the inevitable......
